|A PEAR channel has already been thought in 2008.|
PEAR channel protocol would need to support authenticated accesses so the site can know which users are downloading which packages for packages of authors that require that.
I even tried contacted PEAR people to cooperate and adding authentication support, maybe via oAUTH or something similar. I even told them I was willing to contribute the necessary code. Then I was told by a PEAR guy that he was very busy and then ignored the subject.
Maybe I am not getting this right but I don't know if PEAR people are willing to cooperate. It would be good for everybody, but you know, some people think otherwise.
If anybody more open minded from PEAR is willing to cooperate, I am open to make it happen.
